Chemical giant Monsanto has been ordered to pay $289m (£226m) damages to a man who claimed herbicides containing glyphosate had caused his cancer.
In a landmark case, a Californian jury found that Monsanto knew its Roundup and RangerPro weedkillers were dangerous and failed to warn consumers.
It's the first lawsuit to go to trial alleging a glyphosate link to cancer.
Monsanto denies that glyphosate causes cancer and says it intends to appeal against the ruling.
"The jury got it wrong," vice-president Scott Partridge said
outside the courthouse in San Francisco.
The claimant in the case, groundskeeper Dewayne Johnson, is among more than 5,000 similar plaintiffs across the US.
Correspondents say the California ruling is likely to lead to hundreds of other claims against Monsanto, which was recently bought by the German conglomerate Bayer AG.
Mr Johnson was diagnosed with non-Hodgkin's lymphoma in 2014. His lawyers said he regularly used a form of RangerPro while working at a school in Benicia, California.
The implications of this verdict will be felt far beyond Monsanto's headquarters in Missouri.
Glyphosate is the world's most common weedkiller and the science about its safety is still far from settled.
